235 / 65 / R17 is ( 29 inches in diameter and the tire section width is 9.3 inches ) 245 / 70 / R18 is ( 31.5 inches in diameter and the section width is 9.6 inches )
No, this is a bad swap. If you want to go with a 65 series tire then install a 275/65-15 which is almost identical in overall diameter.
Allot of difference. The 265/75-16 is 5.03% 1.59" larger in overall diameter than the 255/70-16 and is a narrower tire. These 2 sizes are not interchangeable.
255 = width in mm 65 is the aspect ratio 65% of 255 mm in sidewall height. R = radial tire 16 = 16 inch diameter rim so the 70 tire is 1 inch taller overall and at a speedo reading of 60 you will be going 62.1mph
Not unless you change the aspect ratio. For instance: If you have a 215/70-15 tire and you replace it with a 255/70-15 this would be a horrible swap as the 255/70-15 would be 7.58% larger in overall diameter. It is never advisable to go over 3% difference in size. Besides your speedometer would read 55.4 at a true 60 mph. If you want to install a 255 tire you will need to install a 255/60-15 to replace a 215/70-15 which is an excellent swap.
Probably not because of the rim width. The 255 is a wider tire.
NO, it will not.
